FIRS,JTB Morph as NRS,JRB Launch Mandatory Unified Tax ID for Nigerians

ABEOKUTA — In a decisive push toward a fully digital fiscal ecosystem, the Nigeria Revenue Service (NRS) has joined forces with the Joint Revenue Board (JRB) to implement a unified Taxpayer Identification (Tax ID) system, making it mandatory for all taxable individuals and corporate entities across the country.

​The policy shift is backed by Sections 6, 7, and 8 of the Nigeria Tax Administration Act (NTAA) 2025. It cements the structural transition activated on January 1, 2026, which saw the Federal Inland Revenue Service (FIRS) restyled as the NRS, and the Joint Tax Board (JTB) reconstituted as the JRB.

​According to a public directive issued by the revenue authorities on Monday, the newly introduced 13-digit Tax ID replaces the fragmented Tax Identification Number (TIN) framework. The initiative consolidates tax administration across federal, state, and local government tiers to eliminate duplicate profiles, block revenue leakages, and simplify compliance routines.

​Seamless Linkage to NIN and CAC

​Crucially, the authorities emphasized that the new architecture relies on existing foundational identity databases, meaning most citizens will not need to undergo fresh biometric registration.

• ​For Individuals: The National Identification Number (NIN) forms the structural basis of the Tax ID. Individual taxpayers can seamlessly fetch their numbers via a dedicated online portal or by using the USSD code *346# via their NIMC-registered mobile lines.
• ​For Corporate Entities: Registered companies, partnerships, and business names will have their Tax IDs structurally anchored to their Corporate Affairs Commission (CAC) registration details.

​Executive Secretary of the JRB, Olusegun Adesokan, dismissed speculation that the harmonized database would trigger arbitrary bank deductions or automated asset seizures. He maintained that the system was engineered to facilitate economic growth and provide a smoother interface for businesses interacting with financial institutions, employers, and regulatory bodies.

​While the Tax ID remains a mandatory prerequisite for critical financial transactions, opening corporate bank accounts, and securing government contracts, officials confirmed that immediate compliance enforcement focuses on administrative corrections rather than disruptive transaction blocks. Under Section 100 of the NTAA 2025, individuals or entities failing to align with the registry risk a baseline administrative penalty of ₦50,000 in the first month of default, followed by a monthly rolling fine of ₦25,000 for prolonged non-compliance. Exemptions continue to apply to non-earning demographics, including students and dependents.

​API Migration for Banks and MDAs

​With the immediate decommissioning of the legacy TIN Validation API, the NRS has issued a transitional timeline for external institutions. Ministries, Departments, and Agencies (MDAs), commercial banks, and fintech firms that rely on corporate or individual identity validation must update their integration protocols.

​Organisations handling identity verification for individuals, small enterprises, and business names have been directed to interface with the Standardisation and Modernisation Department of the JRB for fresh API access keys. Conversely, institutions validating corporate entities and large conglomerates must coordinate their system migration through the Tax Automation Department of the NRS.
